Concrete, is this the dry powdered supplement? I have one that's just pure Gluc/Chondroitin in powder form, it's called Get Up and Go, and I have a bottle at home. I can double check later what dosage for under 50 pounds is, but Reba gets half teaspoon in her breakfast and another half at night.

I don't know if all of these supplements are created equal, though, so I don't know if it applies to what you're using.
